REM

(programming)
(From "remark") The keyword used in BASIC to introduce a comment (which continues to the end of the line). MS-DOS probably borrowed it from BASIC. Might be used in the form "REM out" meaning to comment out.

comments

Lines of documentation in program source code and batch file scripts. Comments, also called "remarks," are words or symbols that identify a line or a group of lines as text that is not to be compiled or executed.

Comment Quality
The bottom line is that most programmers hate to document, and the quality of the documentation ranges from the ridiculous to the sublime (rarely sublime). The quality of the comments goes a long way in determining the ease with which a program can be changed, not only by other programmers, but also by the original programmer. See obfuscator and comment out.


Sample Codes for Comments/Remarks
When several lines of comments are used, the start and stop symbols for multi-line comments eliminate having to enter a code on each line.
